Answer:

15a + 8b

you multiply 2 by the numbers in the parantasis so our new equasion will be 10a + 6b +5a +2b. You can only add numbers that have THE SAME VARIABLE. So 10a+5a=15a and 6b+2b=8b so our answer is 15a+8b

Help, i'll give a brainliest
Valentin [98]

Answer:

The equation is y=2x + 2

Step-by-step explanation:

4x+2y=7

2y=-4x+7

y=-2x+7/2

Hence, the gradient =-2

Note that: parallel lines share the same gradient

sub m(gradient)=-2 and the point (1,0) into y=mx+c

0=-2(1)+c

c=2

Therefore, the equation in the form of y=mx+c is y=-2x+2
