Answer:
26: x=34
28: x=17
30: m=30
Step-by-step explanation:
<u>26:</u> 2x+22=90
subtract 22
2x=68
divide by 2
x=34
<u>28:</u> 18+3x+21=90
add 18 and 21
3x+39=90
subtract 39
3x=51
divide by 3
x=17
<u>30:</u> 43+87+m+20=180
add 43 and 87 and 20
m+150=180
subtract 150
m=30
Answer: 36+4h=60
36+4h-36=60-36
4h=24
4h÷4=24÷4
h=6
So, after the move they can spend 6 hours there. (6×4=24, 24+36=60, they will spend $60 if they spend 6 hours there, $56 if they spend 5 hours there and don't want to spend $60).

Answer:
y= 11
Step-by-step explanation:
First label the 2 equations.
y= 5x +6 -----(1)
y= x +10 -----(2)
susbt. (1) into (2):
5x +6= x+10
5x -x= 10 -6 <em>(bring</em><em> x terms to 1 side, constant to the </em><em>other)</em>
4x= 4 <em>(</em><em>simplify</em><em>)</em>
x= 4 ÷4
x= 1
susbt. x=1 into (2):
y= 1 +10
y= 11 <em>(</em><em>simplify</em><em>)</em>
Thus, the value of y is 11.
