Question

Determine a raiz de cada equação

a ) 4x+11=1

b) 11x+7=-6

c )5-2x=-17

Answer 1

A) 4x=1-11
4x=-10
X=-10/4

B) 11x= -6-7
11x= -13
X = -13/11

C) 5-2x=-17
2x=-17-5
2x= -22
X=-22/2
X= -11

Answer 2

$a ) 4x+11=1\to\\\\ 4x=1-11\to\\\\ 4x=-10\to\\\\ x= \frac{-10}{4} \to\\\\x= \frac{-5}{2} \\\\\\\\\\ b) 11x+7=-6\to \\\\11x=-6-7\to\\\\ 11x=-13\to\\\\ x= \frac{-13}{11} \\\\\\\\\\c )5-2x=-17\to\\\\ -2x=-17-5\to\\\\ -2x=-22\to \\\\x= \frac{-22}{-2} \to\\\\ x=11$
