Answer:
x=48
Step-by-step explanation:
Substitute y for 0 (0=1/4x - 12)
Multiply both sides of the equation by 4 (0= x-48)
subtract x from both sides (-x = -48)
Change the signs (x=48)
The solution of y=(1/4)x-12 for x will be x = 4y + 48.
What is an expression?
A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
Expression is an equation in which multiplication, division, and summation of all terms are present.
For example 2x + 8t = 0 is a expresion where x and t are variables 2,8 and 0 are constant.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given,
y = (1/4)x - 12
Taking the lowest common multiple right-hand sides
y = (x - 48)4
By cross multiplication
4y = x - 48
By taking 48 into the left-hand side
x = 4y + 48
Hence the solution of expression y=(1/4) x - 12 for x will be x = 4y + 48.
