Step-by-step explanation:
(1)
1) given
-7 (3 + 8x) + 5 ≤ 1 - 62x
2) by distributive property..
-21 - 56x + 5x ≤ 1 - 62x
3) combine like terms
-21 - 51x ≤ 1 - 62x
4) using addition property of order
-21 + 11x ≤ 1
5) using addition property of order
11x ≤ 22
5) using division property of order
x ≤ 2
(2)
1) given that
54 + 2x = 5x - 3(2 + 6x)
2)using distributive property
54 + 2x = 5x - 6 - 18x
3)by combining like terms
54 + 2x = - 13x - 6
4)using subtraction property of equality
54 = -15x - 6
5)using addition property of equality
60 = -15x
6)using division property of equality
-4 = x
