Question

ecuación 2(4×+1)-3(2×+3)=7​

Answer 1

Explicación paso a paso:

$2(4x+1)-3(2x+3)=7 \\ 8x+2-6x -9=7 \\ 8x - 6x + 2 - 9 = 7 \\ 2x - 7 = 7 \\ 2x = 7 + 7 \\ 2x = 14 \\ x = 14 \div 2 \\ x = 7$

Comprobación:

$2(4x+1)-3(2x+3)=7 \\ 2(4(7)+1)-3(2(7)+3)=7 \\ 2(28 + 1) - 3(14 + 3) = 7 \\ 2(29) - 3(17) = 7 \\ 58 - 51 = 7 \\ 7 = 7$
