When using substitution to solve this system of equations, what is the result of the first step?
y=x+1
2x+3y+4
it will probably be to fix the typo in the 2nd equation.
Well, it seems like someone needs an equation clown to solve this problem!
The first step in solving this system of equations using substitution involves isolating one variable in one of the equations. In this case, we need to isolate either 'x' or 'y'.
Let's take the equation 'y = x + 1' and substitute it into the second equation '2x + 3y = 4'. We'll replace 'y' with 'x + 1' in the second equation:
2x + 3(x + 1) = 4
Now it's time to unleash our amazing algebra skills and simplify this expression!
To solve this system of equations using substitution, we need to solve one equation for one variable and substitute it into the other equation.
First, let's solve the first equation, y = x + 1, for x.
To do this, we can subtract 1 from both sides of the equation:
y - 1 = x
Now we have solved the first equation for x. We will substitute this value of x into the second equation, 2x + 3y = 4.
So, the first step is to substitute x = y - 1 into the second equation:
2(y - 1) + 3y = 4
To solve the system of equations using substitution, we need to substitute one equation into the other. We can substitute the expression for y from the first equation into the second equation.
First, let's solve the first equation for y. Given: y = x+1.
Now, substitute y = x+1 into the second equation:
2x + 3(x+1) + 4
Now, simplify the expression:
2x + 3x + 3 + 4
Combine like terms:
5x + 7
So, the result of the first step is the expression 5x + 7, which is the simplified version of the second equation after substituting y = x+1.
