Use substitution to solve the system. X= 2y-5 4x+3y=-9

Mathematics
1 answer:
sergey [27]3 years ago
6 0

Step-by-step explanation:

x=2y-5 - equation 1

4x+3y=-9 -equation 2

Replace equation 1 in equation 2

4(2y-5)+3y=-9

8y-20+3y=-9

11y=-9+20

11y=11

y=11/11

y=1

If y=1, therefore x=2(1)-5=-3

x=-3,y=1

The question is 7a +10 = 2a
Amanda [17]
 7a + 10 = 2a  subtract 2a from both sides
-2a          -2a
 5a + 10 = 0    subtract 10 from both sides
       -10    -10
5a = -10          then divide both sides by 5
/5      /5
a = - 2

Solve for a. A/e -d=c.
Firdavs [7]
Given the literal equation, a/e - d = c:

To solve for "a", add "d" to both sides:
a/e - d + d = c + d
a/e = c + d

Next, multiply both sides by "e" to isolate "a"

(e) a/e = [c + d] (e)

Distribute "e" into the bracket to arrive at the final answer:

a = ce + de
