If x = 7 you substitute all the x in the equation by 7:
y = -2(7) + 5
y = -14 + 5
y = -9
Hope it helped,
Happy homework/ study/ exam!

6 x 106 = 636
3 x 105 = 315
315 x (2) = about 630
If a=-10;then:
a+1=-10+1=-9=b
-9>-10
if a=10; then
a+1=10+1=11=b
11>10
A)The pair of values for a and be are: a=-10, then the value of b would be: -9;
And a=10; then the value of b would be:11;
B) It isn´t possible to create a pair of values for a and be, in wich the numerical relationship shown in the given conditional stament is false, therefore b>a if a+1=b
