4<br>-5a+b=8<br>7a +9b = -32<br>I need to use substitution for this one. Help?​
Sauron [17]

Answer:

<h2>a = -2, b = -2 </h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}-5a+b=8&\text{add}\ 5a\ \text{to both sides}\\7a+9b=-32\end{array}\right\\\\\left\{\begin{array}{ccc}b=5a+8&(1)\\7a+9b=-32&(2)\end{array}\right\\\\\text{Substitute (1) to (2):}\\\\7a+9(5a+8)=-32\qquad\text{use the distributive property}\\\\7a+(9)(5a)+(9)(8)=-32\\\\7a+45a+72=-32\qquad\text{subtract 72 from both sides}\\\\52a=-104\qquad\text{divide both sides by 52}\\\\\boxed{a=-2}\\\\\text{Put the value of}\ a\ \text{to (1):}\\\\b=5(-2)+8\\\\b=-10+8\\\\\boxed{b=-2}

Show your work everywhere you can!<br><br> solve for x. <br><br> c.x/5-12=48
Keith_Richards [23]
Remember you can do anything to an equation as long as you do it to both sides

x/5-12=48
add 12 to both sides
x/5+12-12=48+12
x/5+0=60
x/5=60
multiply bot sides by 5/1
5x/5=60 times 5
x times 5/5=300
x times 1=300
x=300
