That is number one. So what you do is you write that problem down and then you and thenSubtract 13 from both sides and then you do 5-13 they give you -8 and then you divide it by four bring the t down and then Then you do -8÷4 and that gives you -2 and then how do you check your answer is for the t replace it with a -2So now you do four parentheses -2+13 = 5 then you do four times -2 equals -8+13 = 5
