qaws [65]

[ Answer ]

$\boxed{One \ Solution}$

[ Explanation ]

5x + 13 = 13

Solve Equation To Figure Out Solution(s)

Subtract 13 From Both Sides:

5x + 13 - 13 = 13 - 13

Simplify:

5x = 0

Divide Both Sides By 5:

$\frac{5x}{5}$ = $\frac{0}{5}$

Simplify:

X = 0

X = 0. This Means, There Is One Solution To This Algebraic Equation

7(x-2)=28 Can somebody help me and show the steps?

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6
