Solve the equation below for x and check your solution.4x+3=x​

Mathematics
1 answer:
Afina-wow [57]3 years ago
3 0

Answer:

x= -1

Step-by-step explanation:

4x+3=x​

we subtract x to both sides of the equation:

4x -x  +3 = x-x

we have:

3x +3 = 0

we subtract 3  to both sides of the equation:

3x +3 -3 = -3

3x = -3

we divide by 3 both sides of the equation

3x/3 = -3/3

x= -1

we test the result in the original equation:

4x+3=x​

4*(-1) + 3 = -1

-4 +3 = -1

-1 = -1

so finally x= -1

What is the solution for x in the equation. <br> 4x - 3+5 = 2x + 7 - 8x
FrozenT [24]

Answer:

hence solution for x in the equation is  x= 1/2

Step-by-step explanation:

4x - 3+5 = 2x + 7 - 8x

4x +2 = -6x +7

4x +2 =  -6x +7

taking x to the other side then we get

4x+6x = -2+7

10x = 5

divide both side by 10

10x/10 =5/10

x= 1/2

hence solution for x in the equation is  x= 1/2

A farmer plants corn and wheat on a 180-acre farm. the farmer wants to plant three times as many acres of corn as wheat. write a
Anna [14]
Let the number of corn acres be xx and the number of wheat acres be yy.
We are given that:
1- The total number of acres is 180, this means that:
xx + yy = 180 ..............> equation I
2- The number of corn acres is 3 times that of wheat. This means that:
xx = 3yy .........> equation II

Substitute with equation II in equation I to get the value of yy as follows:
xx + yy = 180
3yy + yy = 180
4yy = 180
yy = 45 acres

Now substitute with yy in equation II to get xx as follows:
xx = 3yy
xx = 3*45
xx = 135 acres

Based on the above calculations:
acres of corn = xx = 135 acres
acres of wheat = yy = 45 acres
