Find the solution to the system of equations by substitution.<br> x = y + 1<br> 4x + 3y = -31
lorasvet [3.4K]
X = y + 1...so sub in y + 1 for x in the other equation

4x + 3y = -31
4(y + 1) + 3y = -31...distribute thru the parenthesis
4y + 4 + 3y = -31...subtract 4 from both sides
4y + 3y = -31 - 4....combine like terms
7y = - 35...divide both sides by 7
y = -35/7
y = - 5

now sub -5 in for y in either of the original equations to find x
x = y + 1
x = -5 + 1
x = -4

solution is (-4,-5)

Determine the zeros of the function f(x)= 3x^2-7x 1
OLga [1]
There zeros of a function mean the x-intercepts. simpler way: At what x-values does the graph of the equation intersect the x-axis.

I don't know the if the last term of your function is +1 or -1 , so I did both for you using desmos graphing calculator. 

You can also use quadratic formula, and do the algebra, and see if you get the same answer.
