Hello
x - 7
for x = 23 = 23 - 7 = 16
3 a - b = 12 - 6 = 6
8/t = 8/4 = 2
9 + m = 9 + 1.5 = 10.5
1/2 w + 2 = 1/2 x 1/9 + 2 = 1/18 + 2 = 1/18 + 36/18 = 37/18
5 ( 6.2 + z ) = 50
The domain is x ≥ 1 as x cannot be less than 1 or else it'll become negative in square root which you cannot find a value.
Answer: x = 64
Step-by-step explanation:
70 = 1/2((5x+10)-(3x-2)
(remove the inner bracket)
70 = 1/2(5x+10-3x+2)
(transfer 1/2 to LHS)
70*2 = 2x + 12
140 = 2x+12
(transfer 12 to LHS)
140 - 12 = 2x
128 = 2x
(transfer 2 to LHS)
128/2 = x
=>x = 64
hope it helps
