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!
