Question

4(x+7)=56
5(3-X)=10
ПОмогите решить уравнение.

Answer 1

4(x + 7) = 56
x + 7 = 56 : 4
x + 7 = 14
x = 14 - 7
x = 7

5(3 - x) = 10
3 - x = 10 : 5
3 - x = 2
x = 3 - 2
x = 1

Answer 2

$4x + 28 = 56 \\ 4x = 56 - 28 \\ 4x = 28 \\ x = 28 \div 4 \\ x = 7$
$15 - 5x = 10 \\ - 5x = 10 - 15 \\ - 5x = - 5 \\ x = 1$
