Solve for x. x + 2 = 5
x + 2 = 5 -2 -2 x = 3
100
Solve for x. x/4 = 12
x = 48 Since x is divided by 4, we must do the opposite and multiply both sides by 4. 12 * 4 = 48
100
Solve for x. 2x + 4 = 6
x = 1 2x + 4 = 6 - 4 -4 2x = 2 Divide each side by 2. 2 divided by 2, x = 1.
100
The sum of the mystery number and 8 is 24. Write an equation and solve.
n + 8 = 24 The mystery number is 16.
100
Simplify. 8x - 5(2x + 6)
-2x - 30
200
n - 18 = 47
n = 65
200
13x = 26
x = 2
200
Solve for x. 7x + 3 = 31
x = 4 7x + 3 = 31 - 3 - 3 7x = 28 Since x is being multiplied by 7, you must divide each side by 7. 28 divided by 7, x = 4
200
The difference of the mystery number and 15 is 43. Write an equation and solve.
n - 15 = 43 The mystery number is 58.
200
Identify the coefficients in the following expression and then simplify: 2n - 12 + 4m + 8
2 is the coefficient of n, and 4 is the coefficient of m. 2n - 4 + 4m
300
b + 41 = 23
b = -18
300
-8a = 56
a = -7
300
Solve for z. 23 = -3z - 7
z = -10 -3z - 7 = 23 +7 +7 -3z = 30 Since z is being multiplied by -3, you must divide each side by -3. 30 divided by -3, z = -10
300
The product of the mystery number and -7 is 84. Write an equation and solve.
-7n = 84 The mystery number is -12.
300
Simplify. 4(3x - 8) - 3x(x + 4)
-32 - 3x^2
400
Solve for y. y - 12 = -43
y = -31
400
m/-12 = -16
m = 192
400
Solve for x. 2(-z - 3) + 1 = 19
z = -12
400
The quotient of the mystery number and -4 is -12. Write an equation and solve.
n/-4 = -12 The mystery number is 48.
400

Simplify then evaluate for n = 2 and x = -4 2n + 3x - 8(-2x - 3)

2n +19x + 24 and -48

y - 8.6 = -32.5
y = -23.9
500
Solve for n. n/-1.2 = 4.96
n = -5.952
500
Solve for a. Round your answer to the nearest tenth. -12.4 = -19.1 + -7.9a + 3
a is about .5
500
3 more than twice the mystery number is 31. Write an equation and solve.
3 + 2n = 31 The mystery number is 14.
