Answer: x=70/3

Explanation:

1 Move the negative sign to the left.

-4=-1\times (-\frac{3}{10}x+11)−4=−1×(−

​10

​3

​​ x+11)

2 Simplify \frac{3}{10}x

​10

​3

​​ x to \frac{3x}{10}

​10

​3x

​​ .

-4=-1\times (-\frac{3x}{10}+11)−4=−1×(−

​10

​3x

​​ +11)

3 Simplify 1\times (-\frac{3x}{10}+11)1×(−

​10

​3x

​​ +11) to (-\frac{3x}{10}+11)(−

​10

​3x

​​ +11).

-4=-(-\frac{3x}{10}+11)−4=−(−

​10

​3x

​​ +11)

4 Remove parentheses.

-4=\frac{3x}{10}-11−4=

​10

​3x

​​ −11

5 Add 1111 to both sides.

-4+11=\frac{3x}{10}−4+11=

​10

​3x

​​

6 Simplify -4+11−4+11 to 77.

7=\frac{3x}{10}7=

​10

​3x

​​

7 Multiply both sides by 1010.

7\times 10=3x7×10=3x

8 Simplify 7\times 107×10 to 7070.

70=3x70=3x

9 Divide both sides by 33.

\frac{70}{3}=x

​3

​70

​​ =x

50=x


-4•1(-3/10x+11)
-4=1(-3x/10+11)
-4=-3x/10+11
-4 (-11) =-3x/10+11 (-11)
subtract the numbers.
subtract the numbers again.
-15=-3x/10

I hope this helped :))
