H. 2x – 7 = 3 squared

Lubov Fominskaja [6]

Answer:

h. x=8

Step-by-step explanation:

$2x-7=3^2$

Step 1) Square the 3

$2x-7=9$

2) Add 7 to both sides

$2x-7(+7)=9(+7)$

$2x=16$

3) Divide both sides by 2

$\frac{2x}{2} =\frac{16}{2}$

$x=8$

What is 19-3x=21+x and how do i show my work

Subtract 19 from both sides
-3x=2+x

Subtract x from both sides
-4x=2

Divide both sides by -4
x=-1/2

Final answer: x=-1/2
