Solve for x and show your work 1. 2x=36 2.x/=64 3. 27+6x=99 4. 10x-15=35

1: 18

2: ?

3: 12

4: 5

Step-by-step explanation:

1. 36/2=18

2. Not sure if you missed something here?

3. 6x= 99-27= 72

x=72/6= 12

4. 10x= 35+15=50

x= 50/10= 5

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
