Answer:
x = , y = -1.71
Step-by-step explanation:
sub y = x+4 in the first equation to get:
12 x - 5 (x+4) = -20
Simplify:
12 x - 5 x + 20 = -20
Further simplify:
7 x = - 40
Divie both sides by 7 to get:
x =
--> x = -5.7
Sub x = in the second equation to get:
y = + 4 = -1.71
Answer:
4b+8 = 20
---------------
4b = 20
-------------------
b = 5
Step-by-step explanation:
We need to solve for b in the following equation:
When we multiply each term by 2 the denominator cancels out:
Next, we subtract 8:
Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term
