Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11
I believe 30 is the answer :)
I think this is the answer X = 3 + 1/2y
2 barrettes that measure 1/4-inch each. So we need to add them together
1/4+1/4=2/4-inch
this can be simplified to 1/2-inch
Answer=1/2-inch
