x+5=12
x=7
2x-5=5
x = 5
1/2(x+4)=3
The sum of a number and 5.
x + 5
A= 1/2 bh
Solve for h
h=(2A)/b
2 + x = 15
x = 13
9x+12=-51
x = - 7
3/2(x-5)=4
x = 11
The difference between a number and 7 is 3.
x-7=3
C=2πr+2h
Solve for r
r= ( C−2h)/(2π )
x-13=25
x = 38
3x−2=2x+7
x = 9
6/5(x+3)=10
x = 9
Five less than twice a number is equal to 13.
2x-5=13
P=2l+2w
solve for w
w= (P−2l)/2
x-16=-17
x = - 1
4x+7=6x+5
x = 1
-3/4(2x+8)=9
x=-10
Emma and Liam are deciding between two streaming services. Service A charges $8 per month plus a one-time setup fee of $20. Streaming Service B charges $10 per month with a one-time setup fee of $10. When will both companies cost the same?
5 months
2x+3y=12
solve for y
y = - 2/3x +4
18+x=-14
x = - 32
2(3x−4)+5=4(x+1)−3
x = 2
