Will give brainleist need to turn in by 9 p. m. pls hurry super easy identify the solution of each equation from the list given.
1. 29+d=54; 14,25,26
2. 35=45-n; 10,11,12
3. 6w=30; 5,6,7
4. x/7=3; 20,21,22

1.25

2.10

3.5

4.21

Step-by-step explanation:

29+d=54

d=25

35=45-n

35+n=45

n=10

6w=30

divide by 6

w=5

x/7=3

multiply by 7

x=21

true

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
