1 & 2 Step
3 + x = 7
x = 4
3x - 4 = 2x + 10
x = 14
3(x + 3) = 9
x = 0
Solve for a,
a + b = c
a = c - b
2x + 5 = 5 + 2x
Infinite Solutions
-4x = 16
x = -4
10 - x = 10x - 1
x = 1
-2(2x + 4) + 2x = 12
x = -10
Solve for x,
2x = y
x = y/2
7(2x + 3) = 10x + 4 + 4x
No Solution
6x - 5 = 13
x = 3
-14x + 33 = -16x - 13
x = -23
5 - 4(3 + x) = -35
x = 12
2y - x = z
y = (z + x)/2
5x + 11 - 3x = 3(2x - 1)
x = 3
x/5 - 8 = 1
x = 45
19x - 15 = -31x + 35
x = 1
-(9x - 6) + 15 = -4x - 9
x = 6
Solve for T
P = RTS
T = P/RS
Solve for y
2x + yz = 10
y = (10 - 2x)/z
17 - x/3 = 20
x = -9
1/2x - 4 = -1/2x + 7
x = 11
1 -7(2x + 3) = 17 + 4(-3x - 6) - 1
x = -7
Solve for y,
ax - by = cz
y = -(cz - ax)/b
Solve for Z
X = RTZY + 2
Z = (X - 2)/RTY
