MULTIPLE CHOICE QUESTIONWhat Do You Get When You Combinethese Equations class=

Sagot :

Note that we have the equations

[tex]4a+7b=11[/tex]

and

[tex]-4a-6b=-10[/tex]

If we add this two equations, we get

[tex]4a+7b\text{ +(-4a - 6b) = 4a-4a + 7b -6b = b = 11+(-10) = 1}[/tex]

So, we get b=1.

If we replace this in the first equation, we get

[tex]4a+7\text{ = 11}[/tex]

by subtracting 7 on both sides, we get

[tex]4a\text{ = 11-7 = 4}[/tex]

Finally, if we divide by 4 on both sides, we get

[tex]a=\frac{4}{4}=1[/tex]

So the solution to the equation is a=b=1
