Remember, "less than" indicates a subtraction with the terms in inverted order.

Good job, you got the equations! XD

I'll just help you solve

Multiply the 2nd row by 9
<span>9x+9y=117</span>
<span><span><span>9x+27y=207

</span></span></span>Subtract the 2nd row from the 1st row
<span><span><span>−18y=−90
</span></span></span>Divide both sides by <span>−18</span>
<span><span><span>y=<span><span>−90/</span><span>−18
</span></span></span></span>Two negatives make a positive
<span><span>y=<span><span>90/</span><span>18</span></span></span><span>​​</span></span><span>
y = 5

Substitute 5 into an equation
9x+9(5)=11<span>7
</span>9x+45=11<span>7
</span>Subtract <span>45</span> from both sides
<span><span><span>9x=117−45

</span></span></span>9x=7<span>2
</span>Divide both sides by <span><span>9</span></span>
x = ___

Hope this will help​​</span></span>

Solve the equation.<br> -5=x+3<br> Ox=3<br> Ox=-3<br> Ox=8<br> Ox=-8
weqwewe [10]
Answer:
x= -8

Explain:
You first have to make the variable by itself so you subtract 3 on both sides. The x is by itself and you finish by subtracting -5 to 3 and you get the answer x = -8

Hope this helps

For what value of c is the relation a function (2,8),(12,3),(c,4),(-1,8),(0,3)
Fittoniya [83]
The value of c is { c | c ∈ R, c ∉ {-1,0,2,12} }.
c is a number such that it is not in the set {-1,0,2,12} else we end up with a domain value having multiple range values, contradicting with the definition of a function.
