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.
