Answer: x = 8, x = 5
Explanation:
first problem: first, we collect like terms
3x + 3 = 2x + 11
then, we move the terms around.
3x - 2x = 11 - 3
finally, we collect those like terms and calculate.
x = 8
second problem: first, we rewrite the expression
2 x 3x + 1 = 2x + 21
then, we calculate.
6x + 1 = 2x + 21
next, we move the terms,
6x - 2x = 21 - 1
then, we collect the like terms.
4x = 20
finally, we divide both sides.
x = 5
