It’s 4.5 to go down to my -790
<span>7a+(4+5a)=12a+4
The first step to this is to simplify both sides of the equation.
</span><span>You have to combine all of the like terms first...
(7x + 5x) + (4) = 12x + 4
12x + 4 = 12x + 4
Now the second step is to subtract 12x from both sides....
</span>12x + 4 = 12x + 4
-12x -12x
4 = 4
Now you will subtract four from both sides and get....
0=0

Answer:
Yes, it is a solution
Step-by-step explanation:
9x+7y=-11
-2x-5y=30
substitute 5 for x and -8 for y and test:
9(5)+7(-8)=-11
45-56=-11 , this is true
-2(5)-5(-8)=30
-10+40=30 , this is true also
No
For future reference: When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
