In this question, you're solving for x.

Solve for x:

x + 4.2 = 7

x = 2.8

Answer:

x = 2.8

2m=8

m=4

b 3m/5=-6

3m=-30

m=-10

c 4-5x=19

-5x=15

x=-3

d x/4-10=2

x=48

e -24=8(h+3)

-24=8h+24

For what value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution
hodyreva [135]

The value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2

<h3>System of equation</h3>

For a system of equation to have no solution, the expression on both sides must be different.

Given the system of equation

6x-5y=3 and

3x+ay=1

For the equations to have no solution, the a1/a2= b1/b2

Substitute

6/3 = -5/a


Cross multiply

2 = -5/a

a= -5/2

Hence the value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
