Question

3x-2= 10- x=



ayudaaaaaaa​

Answer 1

$3x - 2 = 10 - x \\ 3x - 2 + x = 10 - x + x \\ 3x - 2 + x = 10 \\ 3x - 2 + x + 2 = 10 + 2 \\ 3x + x = 10 + 2 \\ \\ 3x + x \\ 3x + 1x \\ (3 + 1)x \\ 4x \\ \\ 4x = 10 + 2 \\ (10 + 2) \\ 12 \\ \\ 4x = 12 \\ 4x \div 4 = 12 \div 4 \\ (4 \div 4) \\ 1 \\ (12 \div 4) \\ 3 \\ x = 3$

R/= $x = 3$
