Hey there!

7 + 3x = 22

3x + 7 = 22

SUBTRACT 7 to BOTH SIDES

3x + 7 - 7 = 22 - 7

CANCEL out3 7 - 7 because it give you 0

KEEP: 22 - 7 because it help solve for the x-value

NEW EQUATION: 3x = 22 - 7
SIMPLIFY IT!
3x = 15

DIVIDE 3 to BOTH SIDES

3x/3 = 15/3

CANCEL out3 3/3 because it give you 1

KEEP: 15/3 because it help solve for the x-value

NEW EQUATION: x = 15/3

SIMPLIFY IT!
x = 5


Therefore, the answer: x = 5


Now that we know what your x-value is.. we can substitute it in your next equation


2x

= 2(5)

= 2 + 2 + 2 + 2 + 2

= 4 + 4 + 2

= 8 + 2

= 10

5 = 5

x = 5 ☑️


Therefore, your overall answer is: x = 5


Good luck on your assignment & enjoy your day!
