First solve for x in the first equation. So you'll have to substitute,
5(3x-7)=20
15x-35=20
Then add 35 to both sides.
15x=55
Divide 55 by 15.
So x = 3.66...
Then plug in 3.7 for x in 6x-8
6(3.7)-8
Its approximately 14.2
Answer: y=3x-6
Step-by-step explanation:
Answer:
it could either be n15
15n
because a number multiplied by 5 is
n15
but in mathematics a number comes before a letter when writing a mathematical expression
X=13 i believe!! hope it helps <3
3.2-3x+7
6-3x+7
-7 -7
-1= -3x divide both sides by -3
x=0.3
